testing

Python testing strategies with pytest, fixtures, mocking, parametrize, and coverage.

Use this skill when writing new features, fixing bugs, or refactoring code. Enforces test-driven development with 80%+ coverage including unit, integration, and E2E tests.

Browser automation with persistent page state. Use when asked to navigate websites, fill forms, take screenshots, extract web data, test web apps, or automate browser workflows. Trigger: 'go to [url]', 'click on', 'fill out the form', 'take a screenshot', 'scrape', 'automate',…

Load when running the Spring Boot quality pipeline — mvn test, JaCoCo coverage reporting (jacoco:report, jacoco:check with minimumRatio), Checkstyle or SpotBugs static analysis, OWASP dependency-check:check, Spring Cloud Contract verifier, or configuring GitHub Actions CI…

Load when writing a new feature, fixing a bug, or refactoring code in any stack. Enforces the RED → GREEN → REFACTOR cycle with 80%+ coverage. Use when asked "how do I write this with TDD", "write tests first", "what tests should I write for this", "help me apply TDD to this…

Load when setting up a quality gate sequence, defining done criteria for a feature or bug fix, running the full verification pipeline (compile → unit test → integration test → coverage check → security scan), diagnosing which gate is failing and why, or when the user says…

Activates investigation-to-requirements pipeline — trace root cause then crystallize into actionable spec

Test-Driven Development mode — strict red-green-refactor discipline

QA cycling — test, diagnose, fix, repeat until quality goal is met

Evidence-based verification — fresh test output, acceptance criteria check, PASS/FAIL verdict

Screenshot-based visual QA — compare implementation against design references
